1SAM340000R1001

ABB 1SAM340000R1001, model MS132-0.16T, is a compact 3-pole circuit breaker specially designed for primary-side transformer protection. It provides reliable overload and short-circuit protection without the need for separate fuses, making it suitable for control transformers and industrial electrical panels. The MS132-0.16T has an adjustable current setting range of 0.10–0.16 A and a rated operational current of 0.16 A. Its instantaneous magnetic short-circuit trip is set at approximately 20 times the rated current, or 3.2 A, allowing the breaker to withstand the high inrush currents typically generated when transformers are energized. This device features a Trip Class 10 protection characteristic and provides a rated service short-circuit breaking capacity of up to 100 kA at 400 V AC.
